I MPROVEMENT IN BLIND-AWNINGS.

Specification forming part of Letters Patent No. 202,935, dated April30, 1878; application filed September 17, 1877.

To all whom it may concern.-

Be it known that I, CHARLES P.DEA RBORN, of Boston, in the county ofSuffolk and State of Massachusetts. have invented an ImprovedBlind-Awning, of which the following is a specification:

My invention relates to an improvement in awnings for windows, by whichI am enabled to utilize for the purpose the ordinary window-blinds, sothat they can be converted into an awning in a moment, and at pleasurereadjusted, so that they can be opened and closed to be used as blinds;and the invention consists in the application to the ordinary blinds inuse of peculiar sliding and pivoted hinges, together with a looking-barand supporting-bars; and in certain improvements upon the method ofsecuring the side shades, as will be hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of myimproved awning. Fig. 2 is an interior view of the blinds, showing thelocking-bar. Fig. 3 is a side view of one of the blinds, showing thearrangement of the hinges and supporting-bar. Fig. 4 is a view of thelocking device. Fig. 5 is a perspective view, illustrating the meansadopted for securing the removable side shade.

A B represent the two portions of a window-blind of ordinaryconstruction. To the center cross-piece of the blind A is pivoted alocking-bar, a, having on its outer ends angular projections, whichinterlock with cleats b b, placed one on each center cross-bar of theblinds A B, so that they can be held together for raising to form theawning, and securely fastened when closed.

To the lower outer edge of each of the blinds A B is attached aflatrectangular metal plate, 2', having at its center an elongated slot, z".Upon the face of the plate 13, and secured to it by headed pins passingthrough the slot 6, is a plate, 0, provided with a hinge-socket, k,which fits on a pintle in the window-frame. The plate a is provided witha projection, is, at its upper end, by which it is readily elevated toraise the socket off from the pintle, and thus constitutes a slidinghinge, so as to enable the lower part of the blind to be thrown outwardwhen the blinds are used as an awning.

The use of the slide 0 70 k permits the lower part of the blind to bereleased without the necessity of elevating it bodily, as has beenrequired by previous constructions.

The portion 01 of the hinge which sustains the upper parts of the blindsA B is made in two parts, 61 d, secured together by a pivot, as shown inFigs. 1 and 3, to allow the blinds 'to swingoutward when released fromthe lower hinges, as shown in Fig. 1.

The blinds, when used as an awning, are held in position by means ofbars 6 e, pivoted to the outer sides of the blinds, and provided with aslot at their other end, fitting over pins 9 g in the window-frame.

At the sides of the awning are arranged the shades ff, consisting ofthin strips of wood, pivoted together at their upper ends, and widenedat their lower ends, and connected together so as to open in the form ofa fan. These side shades are arranged to be readily attached to anddetached from the window frame or blinds, as required,it being generallynecessary to have only one side of the awning or window shaded at atime.

The side shade may be made of cloth or other flexible material, ifdesirable.

lis a narrow projecting strip of metal attached to the window-casing,and serving to support the side shade f through the medium of thebracket n, attached to one of the slats of the side shade. A removablekey, m, unites the two parts I and n, so that in the ordinary use of theshade it will not be displaced. By simply withdrawing the key m theshade may be readily detached.

My invention admits of the ordinary blinds in use being readily adaptedfor awnings by the attachment of the sliding and pivoted hinges, asabove described.

What I claim as my invention is- 1. In combination with a windowawninghaving a double hinge at top, the sliding lower hinge, adapted tooperate substantially as described, so that the blind may be detachedfrom the lower hinge without elevating said blind, for the purposesexplained.

from said pintle or connected therewith by elevating or depressing saidbar independently of the blind, substantially as and for the purposesset forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES P. DEARBORN.
